BOTTLE-STOPPER.

SPECIFICATION forming part ofV Letters Patent No. 686,315, datedNovember 12, 1901.

Application tiled April 19, 1901.

To aZZ whom, it may concern:

Be it known that I, CHARLES MARCHAND, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork,have invented certain new and useful Improvements inBottle-Stoppers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

Thisinvention relates to that class of bottle-Stoppers which areprovided with a valve to partially arrest the liow of gas released froma liquid contained in a bottle closed by said stopper.

The objects of my invention are to provide asimple and inexpensivestopper with a valve integral with its body and adapted to closeautomatically a short radial slit or slits made in the inner end of saidbody, being an improvement upon Patent No. 656,698, granted to me August28, 1900, said improvement consisting mainlyin narrow strips ofparaflined paper or cloth retained in said slot to cover the innersurface of the lips of the valve and prevent them from stickingimmovably to each other after having been subjected for a few weeks tothe oxidizing action of the liquid in the bottles, said liquid beinggenerallyperoxid of hydrogen, (H2O2,) the sprin gy lips constituting avalve to resist the passage of a fluid under any desired pressurethrough the slit or slits, but also to permit its passage under aselected pressure, and the relief of the pressure, and therebypreventing the explosion of the bottle or the expulsion of the stopper.I attain these objects by the construction illustrated in theaccompanying drawings, in which-n Figure 1 is a vertical section of theelastic stopper with a central plug therein,which constitutes also a capfor the stopper proper, the parts being made slightly conicalto fitWithin the neck of suitably-formed bottles. Fig. 2 is a vertical sectionof the elastic stopper. Fig. 3 is a vertical section of a stopperconstructed in accordance with my invention and retained within the neckof a bottle. Fig. 4 is a bottom view of the stopper, showing theparaftined strip of paper projecting from said slit in the bottom. Fig.5 is a side View of the stopper. Fig. 6 represents7 in 'a large scale, astrip of parafflned paper adapt- Serial No. 56.589. (No model.)

In the center of the stopper there is a vertical cavity or passage 5,which is extended to about one-eighth of aninch of the bottom 6 toobtain an elastic Wall 7 having said thickness. Vertically through saidwall there are one or more radial slits 8, (threeradial slits beingpreferred,) which are normally closed bythe resilience of its wallsbearing forcibly against each other. As this stopper is intended to beused mainly to close bottles containing peroxid of hydrogen (H2O2) inwater and as said compound gas rapidly oxidizes many substances and evenindia-rubber and causes the lips of the slits to stick to each otheradditional means must be used to prevent their adhesion. These meansconsist ot' one or more narrow strips 13 of paraftined paper or otherantisticking material, each one of which is preferably foldedtransversely, as shown in Fig. 6, and its bent portion pushed into andthrough the slit, where it is retained by the resilience of the lips ofsaid slit. The lower end of the stopper is preferably in the form of atruncated cone, and said portion is coated with a mixture of wax andparaffin 14 to protect the india-rubber of the stopper against theoxidizing action of the gas H2O2.

The valved stopper above described can be used by itself to close theneck of a bottle and automatically relieve the pressure therein, inwhich case the cavity or passage 5 may be made very narrow; but I preferto employ with the elastic stopper a central plug 9, preferably of wood.Said plug is provided with a broad head 10, well adapted to rest uponthe head 3 ofthe stopper and to provide a bearing for the binding-Wire11. The plug 9 fits within the cavity 5, but not closely enough toprevent the passage of gas between said parts when the plug is in itsnormal condition. To prevent the head 10 of the plug from closing thepassage between its bottom and the top of the head 3 of the stopper,there are on top of said head 3 a series of projections 12,

IOO

2. A bottle-stopper consisting of an elastic body having a head extendedhorizontally beyond its periphery, and having also a central cavity, thebottom Wall of said cavity integral with said body having radial slitstherethrough, and'antisticking material retained in said slitssubstantially as described.

In testimony whereof I affix my signature in presence of tWo Witnesses.

CHARLES MARCHAND.
